Preparation

Fill oat flakes, flour, baking powder and sugar into a bowl. Scratch out the vanilla pulp and add to the bowl, then spread pieces of butter on top. Knead the dough; meanwhile pour in maple syrup and milk. Finally, knead in frozen blueberries for 10 seconds.

Put the dough on a foil and form to a roll of 6 cm diameter. Put in the freezer for 45 minutes. Remove the foil, cut the dough into 1 cm thick slices and place in distance of 2 cm on a baking tray.

Bake in pre-heated oven at 160°C air circulation (top and bottom heat 180°C) for 30-35 minutes.
